[Please do, Momo-chan, Ochako certainly does need someone to talk to in that regard, just to air it all out. It'd be difficult, since there most certainly is a hint of jealousy building up as well, but...it'd be best to explain it to a close friend.]

Plus Ultra!! [Pumping her fists up and out of the water with a bit of gusto, Ochako giggles as she accidentally may have splashed her friend a bit, oops! Sorry, Yaomomo.] Eeh...light would fit Hagakure-chan...but I don't know about Mina-chan...

Maybe alchemy? Since that's kind of close to making all kinds of potions and poisons and stuff, right? Sort of like acid!
